The problem
When a person calls, the business keeps a recording and notes. When two agents settle a refund in two seconds, both sides still need a record that holds up if the customer disputes it, a regulator asks, or the agents disagree about what was agreed.
How it works
- Each completed task produces a receipt: the parties, their verified identities, the mandate used, the request, the outcome, and timestamps.
- Both sides sign the receipt.
- The receipt is stored and either party can retrieve it.
- Anyone holding the receipt can later check its hash to show nothing changed.
Open standards
Not covered by A2A. The receipt format is published as an open specification, Emissar Receipt, a draft for comment.
Availability
Specification published for comment. A first version runs in Front Door: when the calling agent asks, each finished task gets a receipt signed by the business, which the agent can countersign and either side can retrieve.
Read the specification: Emissar Receipt v0.1.
Questions
- Where are receipts stored?
- In Front Door, next to the exchange record, for one year; each side also keeps its own copy and can check it without Emissar. Other storage and retention options will be defined with design partners, including regulated industries with fixed retention rules.
